The answer is option 2 and option 6
If these permutations were in a line, then the equation would be n!. But since we are dealing with a circle, it's a little bit different, given that there is no specific beginning or end. This means that <span>you could rotate the circle around n different ways and still have the same circular permutation. Thus, this would be the expression you are looking for:
n!/n, which can be simplified as (n-1)!
The correct answer is the second option.</span>
Answer:
3/14 of a mile
Step-by-step explanation:
It is asking for area. The area of a rectangle is base times height
A = bh
the length can be either the base or the height. It won't matter for this question. Same goes for the width. Lets use 4/7 as the base, and 3/8 as the height.
So
A = (4/7)(3/8)
*When multiplying fractions, multiply the numerators together, and multiply the denominators together, then simplify the resulting fraction.
A = (4/7)(3/8) becomes
A = 12/56 which reduces to
A = 3/14 (both 12 and 56 are divisible by 4)
The GCF of 36 and 81 is 9
36/9 = 4 water balloons
81/9 = 9 beads
Katrina can invite 9 friends, with each getting 4 water balloons and 9 beads
4m + 7a = 14.89
8m + 3a = 18.89
Multiply the first equation by 3 and the second equation by 7
12m + 21a = 44.67
56m + 21a = 132.23
Then subtract the equations and get:
44m=87.56
m=1.99
mangoes cost = $1.99<em>
</em>To find the price of apples, substitute with the mangoes on one equation
4(1.99) + 7a = 14.89
7.96 +7a = 14.89
7a = 6.93
a = 0.99
apples cost = $0.99
